How to get image format

If i have a Image object or BufferedImage , how can i get it's original image format?

But in some cases, if user put an image to
application, when we export the image to a file , the
user want to see the same format image file.i agree, you're right
Of course, we can remember the format when user
select the image, and pass it to export module or
read the bytes from bufferedImage to determine format
by the start bytes. yes, you can keep track of the format
I don't think the two ways are perfect, i don't want
change other modules many codes to remember the image
format, so I want to get a good way to judge the
format from image or buffedImage objectwell, at runtime this will be difficult/impossible, at least for some/most images

Hi,
You can get it from "User" or "Shop" business object.
Try to get User or Shop Business Object as shown below.
BusinessObjectManager bom = (BusinessObjectManager) userSessionData.getBOM(BusinessObjectManager.ISACORE_BOM);
User user = bom.getUser();
char decimalNotation = user.getDecimalPointFormat().getGroupingSeparator();
If you are seeing "1,234.00" then above code will return "."
I hope this information help you to resolve your issue.

How to get OGG format in Logic Studio

Presumably you can convert it to Wav, AIFF or other compatible format using a suitable conversion program (at a guess) - there are convertors to do it the other way round anyway!

// POINT point;
unsigned char*memblock;// for image RGB/8, with RGB/16 is unsigned short

FILE *file;
file = fopen("C:\\abc.txt", "rb");
if( file == NULL)
return;
else
fread(memblock, sizeof(unsigned char), HEIGH * WIDTH *3, file);// for image RGB/8, with RGB/16 is unsigned short
fclose(file);
CClientDC dc(this);
int i = 0;
int j=0;
int k = 0;
for( i = 0; i < WIDTH; i++)
for( j = 0; j < HEIGH; j++)
if (k>WIDTH*HEIGH*3-3)
break;
dc.SetPixel(j, i, RGB(memblock[k],memblock[k+WIDTH*HEIGH],memblock[k+2*WIDTH*HEIGH]));
k+=1;
2. that code is ok for Image RGB/8. But with image RGB/16, now we don't know how Photoshop stores image data, and how to get image data to show???
Please help me?

How to get correct format in file at Application server

Hi,
I am retrieving data MATNR,MAKTX,VENDOR,VENDOR NAME,PRODUCT HIERARCHY,QUANTITY(LABST),BUDAT.
I am downloading the data into .xls file in both presentation and application server.
In presentation I am getting correct format.
Where as in application server I am not getting proper format.
Quantity(MARD-LABST) is not coming proprely.(###6## instead of 36)
How to get it in correct forma?I

symbol means Space
Before transfer the data to File..
condense MARD-LABST and then transfer it.
I guess you are using charcter field LABST while transferring the data to file.
Do not use quantity field directly,please move it to charcter field then condense it.
Thanks

How to get XML format output from Hyperion Financial Reporting

Dears,
We are using Hyperion Financial Reporting to replace FSG in fusion. I found that Hyperion FR report can be exported to html/excel/pdf format. However, I would like the report to export to xml format.It means I only need the xml data source.
Anyone who knows how to get the xml format output from Hyperion FR, is there any avaiable API?

I think if you export the report, you will be able to open the .des file in Notepad/Wordpad and see xml content.

How to get images dynamically from database without file paths in the table field

I have a MS-Access database. I am working with ASP.NET. In the database there is product table in which I have "CodeNo" as a field which is a text field, and the product codes like "SM-R-2035". I also have another field "Image" which is also a text field and which have a file path in it corresponding to the particular product Image (e.g. Images\Products\SM-R-2035.jpg). So far every thing is ok. I have to update this site very frequently and lots of images are added each and every time. Its a tedious work to type the paths and file name every time and it also take a lot of time.
What I am asking is : Is it possible to get images from a specific folder at runtime which is referenced by the "code no" itself and not the file path from the database. (Say at run time the "code no" is referenced from the database and the corresponding image is loaded dynamically from the specified folder). In other word I want to avoid the tedious work of typing.
Can any one help with this issue. Any other simple suggestions are welcome.

All you need to do is simple concatenation to obtain the path for the image file. You didn't mention whether you are using VB.Net, C# or some other language to do your coding.
If the code in your database is SM-R-2035, the file name is SM-R-2035.jpg and the path to the images foilder is Images\Products\SM-R-2035.jpg, Conceptually here is what you need to do:
dim code_var
dim path_var
code_var = the code you obtain from your relevant field in the database
path_var = "Images\Products\" & code_var & ".jpg"
Now path_var is what you would call to obtain the image from your images folder.

How to get image size in bytes

i have to get image size in bytes and accessing image from the a folder

If it's going to be accessed as a file on the filesystem, you can use java.io.File.length() to get the size in bytes.
In other situations...it depends on what you're doing.

Satellite U400 - How to get back formatted partition with HDD Recovery

Hello,
I have bought a new Satellite U400 notebook with Vista Home preinstaled on it.
I went throught initial configuration and after it has been done I realised that HDD partitions do not suits my needs.
So I resised the "Vista" partition (acctually I have shrinked it) and made the "Data" partition bigger.
I did not do anything with hidden partition.
Unfortunately when I did this procedure I formated the "Data" partition.
Now when I want to make backup DVD with TOSHIBA Recovery Disc Creator I got the error message saying that it is not possible because I have formated the "Data" partition.
Are there any suggestion how to solve this error?
The system goes fine, the only thing is that I am not able to backup and restore OS.
Thanks Vecerka

Another possibility besides getting yourself a new copy of recovery DVD is, that you could use 3rd party programs to make an image or backup of your actual system.
I think Norton Ghost or Acronis TrueImage are good programs, but I only used last named one, so can't tell if Norton tool is equal to Acronis.
And if you do not want to order recovery disc online, you always can visit your local ASP for doing this job for you. ;)

How to get custom formating to show in export as HTML CS4

Using a copy of CS4, I am exporting an indesign document that has custom formated words. That is some words are italicized and don't conform to the paragraph style (I have to do this as I get all my documents from Microsoft Word Files). The italicized text shows up as a paragraph style such as "BodyText+" where the normal text is "BodyText". Manually applying a character style to all the italicized text would be impossible.
How can I export as html in this case? Is there a way to format all BodyText+ with a special character style?

Well I guess the find/replace all seems to have set the character styles in the InDesign document, but, it makes no difference in the html output
It still looks like nonitalics italics.
Does anybody know how to make it do something like this:
nonitalics italics ?
I can write the post processing stuff as long as it somehow notes the difference

How to get currency format using pl sql function

Hi all,
I am a newbee on the forum. currently i am facing an issue with the Format of Currency in an rdf report. This is a field of tax amount & i need to make some conditional formatting on this like if the tax amount is Zero then some static note is to be added before this field.
I have tried a lot of functions on it like the one as below:
IF :cp_org_id = 102
AND :invoice_currency_code <> 'CAD'
AND TO_CHAR (NVL (:cf_tax_amount, 0)) = 0
THEN
RETURN (TRUE);
ELSE
RETURN (FALSE);
This is working fine in case of Zero tax amount But gets error out when there some Tax amount exists. It gives a VALUE ERROR in this format Trigger.
Kindly suggest me how to solve this issue with right function. If possible then write the pseudo Code also.
Thanks in advance

In addition to Satyaki:
It might be a 'Reports Thing'.
It works in SQL*Plus (although relying on implicit conversions is a bad idea, as mentioned):
MHO%xe> begin
2 IF 102 = 102
3 AND 'DAC' != 'CAD'
4 AND TO_CHAR (NVL (null, 0)) = 0
5 THEN
6 dbms_output.put_line('TRUE');
7 ELSE
8 dbms_output.put_line('FALSE');
9 end if;
10 end;
11 /
TRUE
PL/SQL-procedure is geslaagd.
